During the test in the video, I was sitting on a chair, and the chair made a sound when I moved it a little. The robotic arm itself only had the sound of the motor running.,The test results show that the 1.59kg banana can still run, and the 2kg Big Coke has obviously lost its step on the third axis. The 3D printing robot arm is limited by the material and cannot perform high-load operation. I personally feel that the 3D printing robot arm is more suitable for robot programming. , path planning, robot construction principles, and host computer development are the purpose of training and teaching.
